WORCESTER, MA; September 08, 2010 - World Energy Solutions, Inc. (NASDAQ: XWES) today announced it has won a major, multi-year contract with the General Services Administration (GSA). The contract provides supply-side energy procurement and management services to the GSA’s Energy Division for its extensive network of federal government agencies. Beginning October 1, 2010 and running through September 30, 2015 — with an option for an additional five-year renewal — the new contract is one of the most important in World Energy’s history.

Over 30 federal agencies, including the Bureau of Prisons, Environmental Protection Agency, Federal Aviation Administration, Internal Revenue Service, National Park Service, Social Security Administration and Veterans Administration, depend on GSA’s Energy Division to help them purchase energy commodities, execute energy strategy, and make sense of the continually changing energy landscape. This makes GSA, which manages more than 11 percent of the Federal government’s total procurement dollars, one of the largest energy buyers in the U.S. The new contract provides GSA a highly-skilled and accountable partner with whom it can address its short, medium and long-term energy challenges anywhere in the country, encompassing services from energy procurement and efficiency to demand response and renewable energy.

“Over the last decade, the GSA has demonstrated tremendous leadership in energy management, embracing state-of-the-art technologies and best practices to bring new efficiencies, greener energy portfolios, and significant cost reductions to a wider and wider sphere of government energy buyers,” said Richard Domaleski, CEO of World Energy. “We view GSA’s long-term contract as tremendous affirmation of our award-winning work together and as our new mandate to help the Energy Division deliver another decade of ‘state of the practice’ solutions to its constituents.”

Dating back to 2001, World Energy has had a long and successful relationship with the GSA. Over this period, GSA and its client agencies have won more than a half dozen awards for energy procurement practices, including a 2002 U.S. Department of Energy Federal Energy Management Award for Innovative Technology for Small Groups for supply procurement in the State of New York; a 2003 White House Closing the Circle Award, recognizing outstanding federal environmental efforts; and a 2008 Environmental Award for pioneering work providing the Statue of Liberty and Ellis Island with green energy. Through World Energy, GSA has procured nearly 11 billion kWh of electricity supply and 100 million Dth of natural gas supply for Federal facilities over the course of hundreds of procurement events.
